Question

I’m dynamically loading a control and passing through text to the control. But i’m getting an unhandeled exception on when i’m setting the public property.

My control is:

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace g247_Test.controls
{
    public partial class carousel_guards : System.Web.UI.UserControl
    {

        protected void Page_Load(object sender, EventArgs e)
        {

        }

        public String pcode
        {
            get
            {
                return pcode;
            }
            set
            {
                pcode = value;
            }
        }
    }
}

Loading the control on the previous page with:

   carousel_guards webUserControl = (carousel_guards)Page.LoadControl("~/controls/carousel-guards.ascx");

            webUserControl.pcode = "rg402eg";
            phGuardsList.Controls.Add(webUserControl);

The error goes on the set { saying just unhandled exception

Answer 1

Your property is referencing itself. You may change it to:

 public String pcode { get; set; }

Or define a private string field and use that:

private string _pcode;

public string Pcode
{
    get { return _pcode; }
    set { _pcode = value; }
}

Also its better if you start the property name with Upper case, (Use Pascal case)
